Answer:
3.5 x 10^22 moles of carbon are there in a 0.70 g (3.5 carat) diamond.
Explanation:
In case of diamond, the number of atoms is the same as the number of molecules.
Answer:
11.0L of carbon dioxide is produced
Explanation:
Balanced equation: 
According to balanced equation, 1 mol of 
produces 1 mol of 
So, 0.489 mol of produces 0.489 mol of
Let's assume behaves ideally.
So, 
where P is pressure, V is volume , n is number of moles, R is gas constant and T is temperature in kelvin
Plug-in all the values in the above equation-
or, 
So, 11.0L of carbon dioxide is produced
Answer:
Option C. Pressure is directly proportional to the absolute temperature.
Explanation:
The ideal gas equation is given as:
PV = nRT
P = nRT/ V
Since n and V are constant, it means that P will be directly proportional to the absolute temperature
Answer:
Exotérmica.
Explanation:
¡Hola!
En este caso, dado que la mayoría de reacciones de combustión son exotérmicas, al generar calor en los productos, es posible inferir que esta reacción, referida a la combustion de metano es exotérmica debido a lo anteriormente mencionado, ya que el término de energía de reacción, 531 kcal, está al lado de los productos, lo que quiere decir que es energía generada.
¡Saludos!
